4. 4 An example of how a vertex (the cross) is affected by two bones (B1 and B2) with the weights 20% and 80%, respectively. Notice how the vertex follows B2 more than B1 due to the weights. 0 (100%). In more mathematical terms, the transformation matrix applied to a vertex is defined as follows: MTot =(w0M0+w1M1…+WnMn) This formula multiplies the bone weight (wx) with the bone transformation matrix (Mx) for all influencing bones and sums up the result (MTot). The resulting matrix is then used to transform the vertex.

In computer graphics, the bones used to animate characters are just a helping structure, something that will never be rendered to the screen. Many fewer bones are needed for digital characters than for humans. Grown humans have over 200 bones, whereas the characters used in computer animation have 30 to 60 bones, depending on the level of control you need. You can see an example of a simplified bone hierarchy in the chapter cover image. 1 A human arm and its corresponding bones. But before you see anything on the screen, there’s quite a lot of behind-the-scenes work you need to tackle first.
